or correct the error.

Description
Fixed disk is not working or not configured properly. Make sure the fixed disk is attached
properly. Run Setup. Find out if the fixed-disk type is correctly identified.
Stuck key on keyboard.
Keyboard not working.
Keyboard controller failed test. May require replacing power supply PCA (contains keyboard
controller).
Unlock the system to proceed.
Monitor type not correctly identified in Setup
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
System RAM failed at offset nnnn of in the 64k block at which the error was detected.
Extended memory not working or not configured properly at offset nnnn . Update to the latest
BIOS version.
The CMOS clock battery indicator shows the battery is dead. Connect the AC adapter for at
least 24 hours; replace the motherboard.
System CMOS has been corrupted or modified incorrectly, perhaps by an application
program that changes data stored in CMOS. The BIOS installed Default Setup Values. If you
do not want these values, enter Setup and enter your own values. If the error persists, check
the system battery. Connect the AC adapter for at least 24 hours; replace the motherboard.
The timer test failed. Requires replacement of motherboard.
Real-time clock fails BIOS test. May require replacement of motherboard.
Previous POST did not complete successfully. POST loads default values and offers to run
Setup. If the failure was caused by incorrect values and they are not corrected, the next boot
will likely fail. This error is cleared the next time the system is booted.
Memory size found by POST differed from CMOS.
Drive A: or B: is present but fails the BIOS POST diskette tests. Make sure the drive is
defined with the proper diskette type in Setup and that the diskette drive is attached correctly.
Type of floppy drive A: not correctly identified in Setup.
Type of floppy drive B: not correctly identified in Setup.
RAM cache failed and BIOS disabled the cache. May require replacement of motherboard. A
disabled cache slows system performance considerably.
CPU socket number for Multi-Processor error.
ServerBIOS2 test error: Cannot write to EISA CMOS.
